This folder contains several files which Charon can use to filter proxies out from your lists. Each file can be changed / modified - and you can create as many new files as you like (for instance, if you want to temporarily filter out a certain range but not modify the old "bad.ini" permanently - this now provides the option. I don't maintain the contents of these files as I feel that "bad" is subjective to the individual. All I've provided here are some sample ones which can be tailored accordingly. Rhino.
